Let me first state that I do not care to win this debate, all i care to do is show my point. Donald trump is incompetent to lead because he is unable to stay level headed in high tention situations. You could say that 'he is not a "politician'", but that is irrelevant because the content of his speech is often derogatory and he lacks specific proposals on most issues. He controls most of the far right republican base and does not have much appeal to moderates in the primary or general election. His support base has been slowly declining because people are starting to see past his "flare" to his lack of substance. That is why Donald Trump will not make make it past the primaries.
